Abstract

Fenomena arcing terjadi akibat kerusakan pada titik sambungan yang menyebabkan longgarnya koneksi dan terbentuknya celah kecil antarkonduktor. Kondisi ini memicu ionisasi udara dan menghasilkan loncatan api listrik. Berdasarkan karakteristiknya, arcing dibedakan menjadi arcing seri dan arcing paralel. Arcing paralel umumnya ditandai dengan kenaikan arus yang signifikan sehingga relatif mudah dideteksi, sedangkan arcing seri sulit dideteksi karena arusnya tidak melebihi batas kerja pengaman seperti MCB dan fuse. Apabila dibiarkan, arcing seri dapat menyebabkan kerusakan komponen, kebakaran, dan membahayakan keselamatan manusia. Pada penelitian ini dirancang sebuah alat deteksi arcing yang bersifat portable sehingga mampu dalam mendeteksi kesalahan busur api di beberapa titik yang fleksibel. Dalam perancangannya, akan dilakukan pengujian alat deteksi arcing pada rangkaian seri dan rangkaian paralel dengan menggunakan variasi pada beban dan nilai resistansi menggunakan sliding rheostat untuk mendapatkan threshold untuk membedakan keadaan kondisi normal dan kondisi busur api. Pengolahan data yang digunakan adalah Discrete Wavelet Transform (DWT) pada rangkaian paralel dan rangkaian seri. Selanjutnya, dalam proses akuisisi data menggunakan mikrokontroler ESP32 dengan menggunakan threshold range 1 A – 2A untuk level dekomposisi 7 dan 1 A untuk level dekomposisi 4. Hasil alat deteksi arcing dalam mendeteksi keadaan busur api listrik DC dapat diimplementasikan langsung pada sistem DC photovoltaic dengan akurasi 74% untuk arcing seri dan 91,3% untuk arcing paralel, serta mampu memberikan informasi kepada pengguna untuk monitoring terkait instalasi DC melalui memori dan tampilan pada alat deteksi arcing dengan baik dan akurat.

Arcing phenomena occur due to damage at connection points, causing loose connections and the formation of small gaps between conductors. This condition triggers air ionization and produces an electrical arc discharge. Based on its characteristics, arcing is classified into series arcing and parallel arcing. Parallel arcing is generally characterized by a significant increase in current, making it relatively easier to detect, whereas series arcing is difficult to detect because its current does not exceed the operating limits of protective devices such as Miniature Circuit Breakers (MCBs) and fuses. If left undetected, series arcing can cause component damage, fire hazards, and endanger human safety. In this study, a portable arcing detection device was designed to enable flexible detection of arc faults at various locations. The proposed device was tested on series and parallel arcing circuits by applying load variations and resistance adjustments using a sliding rheostat to determine the threshold for distinguishing normal operating conditions from arc fault conditions. The data processing method utilized was the Discrete Wavelet Transform (DWT) for both series and parallel arcing detection. Furthermore, data acquisition was performed using an ESP32 microcontroller with threshold ranges of 1 A–2 A at decomposition level 7 and 1 A at decomposition level 4. The developed DC electrical arc fault detection device can be directly implemented in photovoltaic DC systems, achieving detection accuracies of 74% for series arcing and 91.3% for parallel arcing. In addition, the device is capable of providing accurate monitoring information regarding DC installations through data storage and real-time display features integrated into the arcing detection device.
